AI Technical Summary

Technical Problem

In wireless communications, the existing handover process between base stations is inefficient due to the unnecessary determination and activation of signaling plane security protection algorithms, leading to increased network overheads and preparation time, which reduces handover efficiency.

Method used

A method where a first access network device determines only a user plane protection algorithm based on the correspondence between user plane information and a security policy, without enabling signaling plane protection, thereby reducing network overheads and improving handover efficiency.

Benefits of technology

This approach reduces network overheads and saves time for the access network device to prepare for handover, thereby enhancing the efficiency of the handover process while ensuring security.

Abstract

This application relates to the field of wireless communications technologies. Embodiments of this application provide a security protection method, an apparatus, and a system, to resolve a problem of low efficiency in handing over a terminal between serving base stations. The method in this application includes: receiving, by a target access network device, a correspondence between user plane information and a security policy from a source access network device; and determining, by the target access network device based on the correspondence between user plane information and a security policy, a first user plane protection algorithm corresponding to the user plane information, where the first user plane protection algorithm includes one or both of a user plane encryption algorithm and a user plane integrity protection algorithm. This application is applicable to a procedure in which the terminal is handed over between serving base stations.
